Is it possible to post some pics of the affliction ?

Posted. Thank you, Ian.

The headstock was reglued but the crack has a slight lip.

The finish looks fairly thick. You may be able to level it and polish it out. If you were being extra cautious, you could use Fill n Finish to level it out a little bit to pick up the slack in the difference.

To level it out would I be able to wet sand it with 2000 grit or will that scratch it? Thanks Ian.

To level and polish, you would want to go through the grits and polishing compounds more than that.
I would level it with 600 grit at least. Then go through the grits 1000, 1500 and then 2000 before polishing with a compound like #7 Maguires, or buffing it on a buffing wheel.
Is this your first time level sanding and polishing something back up to a high sheen ?
-
Yes. Where can I get #7 Maguire’s?

You can get the Meguires from Harbor Freight now. Or you can order it online. Is this your guitar or a customer’s guitar ?

Missed this reply – yes, for a customer.
